Characteristics of Garbage Sorter

With the increase of the urban population, waste sorting machines have become popular in many countries. Recently, municipal waste has shown an increasing trend. Facing the large amount of waste generated by human beings, how do we quickly realize the classification of waste? The answer is a fully automatic garbage sorter. This kind of recycling equipment makes garbage sorting easier. At the same time, the machine will save a lot of labor costs.

The garbage sorter is designed based on the principle of reducing the volume of garbage and turning waste into treasure. By using various efficient garbage sorting systems, we can obtain organic, plastic, metal, brick, stone, etc. from the garbage. The classification rate of the above garbage can reach more than 85%, and the classification rate of film plastic can reach more than 90%.

Do you know the characteristics of the Sorting machine MSW china?

1. Rotating screen machine. The rotary screen machine is mainly used to select large materials larger than 50mm and small materials smaller than 50mm. This process effectively divides waste into two types. In addition, according to the different needs of customers, we can also add blades inside the rotary screen to achieve the breaking effect.

2. Smooth automatic document feeder. This paper feeder can automatically transfer the garbage to the next garbage sorting process, thus saving manpower. In addition, the machine can evenly distribute garbage on the belt, so that the next operation is more smooth.

3. PLC system. The PLC control system can monitor the entire working process of the solid waste management system. Once anything unpredictable happens, we can make adjustments in time. Therefore, the machine greatly guarantees the safety of the garbage sorting equipment.

4. Comprehensive winnowing machine. The comprehensive winnowing machine adopts several garbage classification principles, such as specific gravity method, volume method, cyclone separation method, etc. Waste is mainly divided into three types: plastic film and mixed materials (hard plastic, rubber products, miscellaneous paper). , Textiles, etc.) and heavy objects (bricks, stones, rubber overshoes, glass, etc.). After being processed by this garbage classifier, the sorting rate is greatly improved.

What materials can be sorted from garbage? What can these classified materials do?

As we all know, garbage is composed of plastic, tree branches, chicken manure and other different wastes. In different countries, there is a big gap between the composition of waste. We want to know your detailed information and will design a suitable solid waste recycling plant for you.

1. Waste plastic. There are three ways to recycle waste plastics. The first is to use a waste plastic pyrolysis machine, which can turn plastic into oil. Secondly, certain materials in plastics can be used as rubber reinforcing agents. Third, we can sell waste plastics to other industries to make new plastic products.

2. Stone, sand, and waste building materials. Do you think these wastes are useless? However, we can use these wastes to make bricks through the brick machine production line. Nowadays, the technology of making bricks from the mud, stones, sand or carbon black in pyrolysis garbage is fully mature.

3. Organic matter. After selecting some unusable materials, we can send the organic matter to the fermentation system, and then the system will produce biogas as energy.

4. Scrap metal. After packaging with a packaging machine, scrap metal can be sold directly to other industries to manufacture new metal products.

Criteria for Good Garbage Classification

So far, there is no scientific and unified criterion for judging whether the garbage classification is good or not.

How much waste is sorted out and reduced through waste sorting equipment, or how much money is spent sorting out a tonne of waste? We will find that some places have spent tens of millions of yuan for several years, but only tens of thousands of tons of renewable resources are recycled (not including kitchen waste). Calculated according to the cost of recycling per ton, up to a few thousand or even tens of thousands of yuan per ton, such an approach is definitely unsustainable and unrepeatable.

The key issue is that, in the end, it was discovered that after several years of garbage classification, the effect of garbage classification was not obvious, and there were no obvious “beneficiaries”. The "benefits" here are mainly economic benefits. In the end, everyone was busy, and until the end, everyone was tired but to no avail.

So what are the real criteria for classifying rubbish? According to Waste Sorting Machine MSW China Manufacturer; There are three criteria:

First, whether it is conducive to sustainable and harmless household garbage, recycling, and source reduction.The so-called sustainable means that it can continue continuously, which requires low operating costs and not excessive financial input. Harmlessness is the foundation, and resource recovery is the guarantee, that is, how much waste is allocated for recycling treatment and utilization and no longer enters landfill sites. In the documents of the Ministry of Housing and Urban-rural Development, the utilization rate of classified resources reaches 35%. The key is to reduce the front source, which can be promoted or pushed back by garbage classification. For example, the daily amount of garbage per person can be reduced from 1.12 kg before to 0.39 kg in 2009 by garbage classification, which can be reduced by 65%. Through garbage classification, South Korea produced 2.3 kilograms of waste per capita per day in 1995, compared with 0.95 kilograms in 2006, a decrease of 58.7%.

Second, is it beneficial to the residents' sense of gain and happiness? First clarify the attributes of garbage, because garbage is a pollutant, you should first pay; because it is sorted, you should pay for labor, and you should have income, especially economic income. However, due to historical reasons, the previously mixed waste treatment fee was not charged or not charged in full, so the income through waste classification and reduction cannot be reflected. This situation needs to be corrected and becomes "multiple mixed wastes. Charge, sort garbage, and pay less". At the same time, the residential environment of the community has become tidy and clean due to garbage classification, which improves the beautification of the living environment, and the residents have a sense of gain and happiness.

Third, is it conducive to reducing the overall government financial input? When garbage sorting starts, the government needs to increase investment appropriately, but from a long-term and overall perspective, as garbage is recycled and the source is reduced, the garbage removal and disposal fees will be reduced, and the service life of the back-end factories will be extended. This will produce economic benefits. Therefore, the success of garbage classification will not only produce ecological and social benefits, but also industrial economic benefits.

Why Do We Need A Biogas Plant?

Biogas is advertised by some as indispensable to creating around the economy, however just how advantageous is it as a power source? Do we need a biogas plant?

1. What is biogas energy?

Biogas is a kind of biofuel that is normally produced from the decay of organic waste. When raw material, such as food scraps as well as pet waste, breaks down in an anaerobic setting (an atmosphere lacking oxygen) they release a blend of gases, mainly methane as well as co2. Because this decomposition occurs in an anaerobic setting, the process of producing biogas is likewise known as anaerobic digestion.

2. Why choose marsh gas?

By transforming natural waste into energy, biogas is making use of natures sophisticated tendency to recycle substances into efficient resources. Biogas generation recoups waste products that would certainly or else contaminate landfills; stops using toxic chemicals in sewer treatment plants, and also conserves money, energy, and also material by treating waste on-site. Furthermore, biogas usage does not need fossil fuel removal to create power.

Instead, bio gas takes a problematic gas as well as converts it into a much safer type. Much more particularly, the methane material present in decaying waste is exchanged co2. Methane gas has about 20 to 30 times the heat-trapping capabilities of co2. This implies that when a decomposing loaf of bread converts right into biogas, the loafs environmental influence will certainly have to do with 10 times less potent than if it was delegated rot in a landfill.

Biogas Plant

3. Functioning of a Biogas Plant

The fresh pet manure is stored in a collection storage tank before its handling to the homogenization storage tank which is equipped with a mixer to promote homogenization of the waste stream. The consistently mixed waste is gone through a macerator to acquire a consistent particle size of 5-10 mm as well as pumped into suitable-capacity anaerobic digesters where the stabilizing of natural waste happens.

In anaerobic food digestion, natural material is converted to biogas by a collection of bacteria teams into methane and also carbon dioxide. The majority of commercially running digesters are plug flow as well as complete-mix activators operating at mesophilic temperature levels. The type of digester utilized differs with the consistency and also solids content of the feedstock, with capital investment aspects, and also with the key purpose of food digestion. Biogas consists of a substantial quantity of hydrogen sulfide (H2S) gas which requires to be removed off due to its extremely corrosive nature. The removal of H2S happens in an organic desulphurization system in which a minimal quantity of air is added to biogas in the visibility of specialized cardiovascular bacteria which oxidizes H2S into essential sulfur.

4. Advantage of bio gas plant.

Biogas plants depend on anaerobic food digestion, a fermentation procedure in which waste is absorbed by microbes to create methane gas (biogas). The waste can be converted into biofertilizer and also spread directly onto fields, or the biogas itself can be utilized reciprocally with natural gas .

Biogas could be especially beneficial in-country or poorer areas due to the affordable set-up as well as the schedule of waste materials. Virtually any kind of organic waste can be made use of while doing so, though aspects such as pH and also temperature level influence gas manufacturing.

5. The path to a circular economy

Sourcing power from biogas seems an excellent option to two problems faced in the modern globe: mounting waste as well as the requirement to rapidly decarbonize in the face of increasingly unpredictable international temperatures.

Operation Steps of Vertical Baler

Waste paper baler is packaging machinery used to compress waste paper items. Used by various waste paper factories, old waste recycling companies, and other units and enterprises to compress a variety of recyclable fluffy waste products such as domestic waste, industrial waste, plastic, film, pasture, straw, cotton, iron filings, aluminum filings, and scrap Bale.

The baler can double the volume of waste products and increase the density of objects to make them easy to transport and store. It is one of the important equipment in the recycling of waste products.

Waste paper balers are mainly divided into two common models, vertical and horizontal. This article briefly summarizes the operation methods of the vertical baler for reference by industry personnel.

Vertical waste paper baler is a mechatronic product, mainly composed of mechanical systems, control systems, monitoring systems, and power systems. The specific organization structure can refer to the following figure.

Generally, the vertical waste paper baler is equipped with anti-rebound barbs, safety switches, and opening safety interlocking mechanisms to play a role of safety protection. However, there are many types of vertical baler brands circulating in the market, so I cannot describe them in detail here.

Different balers have different relevant parameters. The main difference lies in the motor power and the bale size.

Waste Paper Baler

Features of the vertical baler

The vertical waste paper baler has the characteristics of convenient operation and maintenance, safety and energy-saving, and low investment cost of equipment basic engineering.

In terms of installation, the vertical baler does not require foot screws during installation, just choose a flat ground to be stable.

In terms of power, some models support diesel engine power. When used in places without power, diesel engines can be used as power.

In terms of structure, the push cylinder and the push head of the vertical waste paper baler are connected by a spherical structure, which has good reliability and long service life of the oil seal. At the same time, there is a distributed shearing knife at the feeding port, which has high cutting efficiency.

—Safe operation of waste paper baler —

The waste paper packing process can be divided into four steps: adding materials, suppressing materials, binding materials, and turning out the materials. As a piece of professional equipment, we must pay attention to safe operation in operation to avoid damage to the equipment due to improper operation.

the first:

Place it flat when adding scrap

In the process of adding materials, it is necessary to pay attention to the input materials that must be placed in parallel and even, to prevent the machine from being easily damaged by tilting when the pressure plate is pressed down.

second:

Pay attention to the load when suppressing materials

Generally, the running-in period of a new hydraulic baler is about 3 months. Do not overpressure during the running-in period, as overpressure will shorten the service life of the equipment.

In daily use, if the machine is pressed for a long time, the motor load will increase, the current will increase, the hydraulic oil will rise sharply, and the cylinder and tubing will increase in tension, which will also shorten the life of the machine.

third:

The operator needs to stand in the correct position

When the vertical waste paper baler is started, the pressing plate compresses the material downward. The material will generate a great external thrust due to the compression. When the door lock is damaged, the door will receive a great internal thrust, which may automatically pop up and the door will pop up. The force will be great, if the operator is standing in front of the door, other injuries may occur.

Therefore, the operator must not stand in front of the door. The correct standing position should be holding the handle of the manual reversing valve with the right hand, and the body is at a 45-degree angle with the round column, so as to avoid hurting people when the front door and side door pop out.

fourth:

Beware of the elasticity of the door when picking up

After the compression is completed, when the door is opened to pick up the goods, the door will automatically pop out due to the outward thrust of the compressed material. When it is ejected, the elastic force is large and the door will move forward for a certain distance, so people cannot stand in front of the door when opening the door. So as to avoid accidents.

Landfill, Incineration and Composting

The national waste treatment principle is as follows: First, it is to recycle as much as possible, including as far as possible the recycling of biodegradable organic matter such as composting and anaerobic digestion; the second is to incinerate combustibles as much as possible; The last is to landfill the garbage that cannot be processed in other ways. The main characteristics of the three methods of landfilling, incineration, and composting are introduced below, and a simple comparison is made.

Landfill: The landfill is divided into two technologies: simple landfill and sanitary landfill. Simple landfilling generally involves choosing a mountain col or digging a huge pit in the suburbs and dumping the collected garbage into it. When the garbage is filled, some earth-covering work is done on the garbage dump to cover the garbage. A simple landfill has low investment and simple operation, but it occupies a large area. The landfill leachate causes serious pollution to groundwater and soil. The odor generated by garbage dumping seriously affects air quality. Sanitary landfill is to lay an anti-seepage isolation layer at the bottom of the landfill, discharge the generated leachate for treatment, prevent the leachate from polluting the groundwater and soil, and at the same time export the methane produced by the fermentation of the waste for use or reasonable discharge. The advantages of the sanitary landfills are strong applicability, can accept various wastes, large processing capacity, and low initial investment and operating costs. The disadvantage is that the landfill has strict site requirements, relatively difficult site selection, and large area. The landfill is generally suitable for areas with sparse population and rich land resources. Sanitary landfill is the main method adopted in China's garbage disposal at this stage.

Incineration System

Garbage incineration: Garbage incineration is a high-temperature heat treatment technology, which means that garbage is sent to an incinerator for incineration to reduce the volume, volume, and harmlessness of garbage disposal. In industrially developed countries, the incineration method has been widely used. The advantages of the incineration system are: (1) Small footprint, which is particularly important for cities with tight land use; (2) High degree of capacity reduction, generally, 90% reduction in capacity and 80% reduction in capacity (3) Thorough disinfection, the high temperature generated by the incinerator can completely decompose the harmful substances in the garbage, and completely kill the pathogens in the garbage; the gas and smoke produced by the combustion are discharged after treatment, and the secondary pollution is small; ( 4) The thermal energy generated by waste incineration can be used for power generation and heating, turning waste into treasure. Of course, the incineration method also has its limitations: large investment, complicated operation, high management cost, flue gas generated during incineration, etc. Large funds can be effectively processed.

Garbage composting: Composting is the separation of organic components in the garbage, adding certain additives for fermentation, and then further processing into fertilizer. The Composting project has a simple process and is suitable for processing garbage with high perishable organic matter, but it cannot completely dispose of all garbage, and other treatment methods are generally required at the same time. Due to the unstable quality of the fertilizer produced by garbage composting, it has encountered market problems. Therefore, in the past 20 years, the treatment of urban garbage composting in our country is experiencing a process of stagnation or even shrinking.

How to Improve the Efficiency of Waste Paper Baler?

The carton packer frame consists of 4 sets of wire devices installed in a frame, the central axis of the lead frame is relative to the pressure frame, the pressure frame moves in the horizontal direction, the hydraulic motor function, the pressure frame is welded, the bottom is equipped with wheels, and the hydraulic cylinder drives Can move horizontally along the guide rail. The lifting platform is mainly composed of two beam bolts, which can be moved up and down in the vertical direction by driving the lifting platform with 2 hydraulic cylinders.

The waste paper baling machine press frame and press frame structure are similar, but the above arrangement of 4 groups of heads, 1 set of wire feeding device. The baling head of the waste paper hydraulic baler is the most complicated. Most of the interlocking actions affect the structure of the entire equipment. The heads of the hydraulic waste paper balers have the same structure and can be interchanged. A total of 4 sets of wire feeding devices, each corresponding to a packaging head, each including packaging line conveying equipment and packaging line tension device.

The hydraulic waste paper box baler is mainly composed of two main bases on the surface with wear-resistant rails. The frame pressing wheel pushes the hydraulic cylinder to operate along the two outer tracks. In addition to mechanical parts and a hydraulic station. It can be seen from the above description that all the movements of the waste paper hydraulic baler are completed by fluid power.

How to improve the working efficiency of waste paper balers? In the modern society, the waste paper balers industry has several times of research and development and innovation, coupled with the all-round introduction of leading foreign products, to achieve a new high-efficiency product that combines full automation and intelligence. Packer equipment. So what are the conditions that determine the labor production efficiency of the waste paper baler, and how to improve the efficiency, let us analyze it carefully here.

Waste Paper Baling Machine

The production efficiency of waste paper baler is the key factor that most directly affects this problem: the type and specification of the baler, the different output of the model, and the different specifications directly determine the labor production efficiency of the baler. The production efficiency of the conventional waste paper baler is higher than that of the baler with a door at the discharge port.

The high-efficiency production of waste paper baler is also inseparable from the performance of the cylinder of the baler. The performance of the cylinder determines the stability of the baler. To ensure the high-efficiency production performance of the baler equipment, you must choose a baler manufacturer with exquisite cylinder production technology.

The quality of the hydraulic oil selected by the waste paper baler directly determines whether the cylinder can maximize production efficiency, and also affects the failure rate and service life of the cylinder.
